Objective ?To compare the medial and lateral rotations of the shoulders and the distances between the coracoid process and the cubital fossa of non-athletic individuals to those of elite squash players. Method ?The cross-sectional study was performed between March and August 2017. Male and female non-athletes ( n ?=?628) were selected at the Orthopedic Emergency Service of our institution. The inclusion criteria were age between 18 and 60 years, no physical disabilities or cognitive impairments and absence of pain in the upper limbs. https://www.selleckchem.com/products/merbarone.html Elite squash players ( n? =?30) of various nationalities were selected at an event held in our city. All of the athletes had practiced this sport under high performance requirements for?&gt;?10 years and/or 10.000?hours, and all were asymptomatic. Demographic and clinical data were collected through interviews, while physical examinations and shoulder assessments were performed by a single orthopedic practitioner. Results ?If compared with non-athletes, elite squash players presented significant ( p? less then ?0.001) mean losses of 23°34' in medial rotation and significant ( p ? less then ?0.003) mean gains of 10°23' in lateral rotation of the dominant shoulders. There was a significant difference ( p ? less then ?0.008) between non-athletes and athletes regarding the distance between the coracoid process and the cubital fossa in the dominant arm. Conclusion ?Intensive squash practice causes adaptive changes that trigger glenohumeral medial rotation deficit, accompanied by significant lateral rotation gain, and can generate pathogenic alterations in the shoulder.Objectives ?The aim of the present study was to describe the dimensions of the coracoid grafts in our Latarjet surgeries and compare them with the results described in the literature. In addition, the feasibility of the 7-millimeter rule was verified. Methods ?Individuals with anterior glenohumeral instability with or without bone loss participated in the present study. The dimensions of 31 coracoid process grafts of patients who were submitted to the Latarjet surgical technique were measured with an analogical caliper and recorded for posterior analysis. Results ?The dimensions of the coracoid graft did not show statistically significant differences related to gender. The graft width obtained from our sample presented similarities with the dimensions reported in the literature. However, the length and thickness were smaller when compared to the reference study (Young et al, 2013). 15 The 7-millimeter rule was considered feasible regarding the graft dimensions obtained from our sample. Conclusion ?The coracoid graft dimensions were similar to the dimensions described in the literature regarding width, but the same was not found for length and thickness; and the 7-millimeter rule was feasible regarding the graft dimensions obtained from our sample.Objective ?Arthroscopic Latarjet has been performed with the aim to be an accurate technique with a low incidence of complications. The aim of the present study was to briefly describe the technique and to evaluate the shot-term complications following arthroscopic Latarjet procedure to correct anterior shoulder dislocation with glenoid bone loss. Methods ?Retrospective study with 30 subjects with anterior shoulder instability, submitted to arthroscopic Latarjet. Intraoperative and short-term postoperative complications were recorded, as well as the rate of revision surgery. Results ?Five cases had complication (16.7%), and in the last 10 cases no complication occurred. In 1 case (3.3%), it was required to reverse for open surgery due to a fracture of the coracoid process during fixation in the glenoid. No other intraoperative complication occurred. No infection was observed. Two cases (6.7%) evolved with temporary neuropraxia of the musculocutaneous nerve, totally reversed with physiotherapy. With a follow-up from 6 to 26 months, 2 patients (6.7%) required a new intervention for graft/screws removal and release of the joint due to excessive limitation in external rotation. There was no case of recurrence. Conclusion ?Even in an initial learning curve, arthroscopic Latarjet demonstrated a low rate of short-tem complications and was a safe procedure for treating anterior dislocation of the shoulder with glenoid bone loss.Objectives ?The objective of the present study is to evaluate the intraobserver and interobserver reliability of the Albertoni classification for mallet finger. Evaluation of goniometer device application is also an objective. Methods ?A total of 10 lateral radiographs of patients with mallet finger were selected and measured by 60 orthopedic surgeons with and without the use of goniometer. Results ?The intra- and interobserver reliability coefficients found were high. With the use of a goniometer, the interobserver reliability coefficient was even higher, but without statistical relevance. Conclusion ?The Albertoni classification showed high intraobserver and interobserver reliability in assessing mallet finger lesions, and the goniometer is dispensable for this purpose.Objective ?To evaluate 15 patients with ruptured distal biceps tendon submitted to reinsertion via a single, anterior and transverse approach using two anchors. They were submitted to a rehabilitation protocol and, within six months, to an evaluation of the range of motion and strength intensity during flexion and supination of the operated elbow. Methods ?The data were collected prospectively, and were analyzed through the Mann-Whitney test and the mixed-model test to evaluate the force between the operated and non-operated elbows. Results ?A total of 80% of the patients were men, 60% were injured on the dominant side, 46% were manual workers, and 73% led sedentary lifestyles. The use of anabolic steroids was reported by two patients. After the treatment, the patients recovered supination strength by 98% and flexion by 94%. According to the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, 73% of the patients presented the score expected of a normal population. Conclusion ?The single, anterior and transverse approach associated with tendon repair using anchors was esthetically satisfactory, with good strength recovery during flexion and supination, and no occurrence of heterotopic ossification.
